Scopes

1.4303 - X4CrNi18-12 is a low decarburrized, austenitic stainless steel in many applications. There is the advantage in high-alloyed nickel content to increased resistance to corrosion compared with 1.4301 or 1.4306.

The field of application contains chemical industry, mechanical engineering, electronic equipment, food and beverage industry and automotive industry. In addition, this stainless material is often selected for bolts, studs, and nuts (turbine industry). 

Characteristics

Weldability:
The material 1.4303 X4CrNi18-12 is good suitable for welding constructions. An interpass temperature of 150°C should not be exceeded and a post weld heat treating (PWTH) is not necessary. It´s possible to get tempering colours that results from the heat of welding, which is removeable by grinding to restore the corrosion resistance.

Mechanical Properties:

Hardness:max. 215 HBW
0,2 %-Yield strength:> 180 MPa
Tensile strength:460 to 680 MPa
Reduction in area (transverseongitudinal):min. 35%
Impact test (ISO-V) longitudinal:min. 60 J

Advantages of saw cut

The machining by our saws is a mechanical step of processing of this material products, which results in a significantly lower unintended deformation and increased hardness for the existing  structure, such as the thermal cutting. This approach allows finishing of the workpiece by milling or drilling, immediately. So it isn´t necessary to anneal the material or make any similar operation beforehand.
